I was really pleasantly surprised how well Linix is running. PopOS by System76 is based on Ubuntu but they tweaked it a lot with their own version of Gnome. It's really well made and everything worked out of the box. And yes, you are absolutely right, it is not automatically safer or more private. But it has a lot of possibilities.
And it is awesome that you are in control of everything. I mean you can change every aspect of the UI to your liking without any hassle or fumbling in a registry.
PopOS is one of those distros that I do not like. I really do not believe in making "yet another distro" . Some distros has a reason to exist like Arch (community independent from corporate), Linux Mint (for the simple user), or Puppy Linux but then you are hoards that are just bloat and more of the same thing like KDE Neon, PopOS, Garuda, Elementary, MX Linux, Solus...etc
I think most of these people instead of defragmenting the linux even further and starving for donations because they can not sustain their own, maybe get together and make a few linux varieties that work really work and are polished.
